I am an Associate Professor in aquatic ecology and Leader of the Aquatic Ecology and Restoration Research Centre at the University of New England. I have over 18 years experience in research in aquatic ecosystems in coastal and inland rivers and wetlands of eastern Australia. My research expertise has a focus on the effective management and restoration of freshwater ecosystems and covers areas such as:
- Design and implementation of monitoring programs to assess the ecological health of wetland, river and estuarine ecosystems.
- Biogeochemistry and ecosystem function of aquatic systems.
- Biodiversity and foodweb analysis of aquatic systems.
- Design of best-practice models for river restoration and assessing ecological outcomes of on-ground restoration practices.
I teach a number of units with a focus on the ecology, management and restoration of aquatic ecosystems, and have recently co-authored the new textbook 'Australian Freshwater Ecology' that is being used as a textbook in many Australian universities.

My research projects have a strong focus on investigating the ecology of wetland, river and estuarine ecosystems – how populations and communities interact with their physical environment. I am particularly interested in understanding the fundamental biogeochemical processes such as nutrient and organic matter cycling, and ecosystem metabolism that support aquatic food webs.
- Aquatic species ecology - microbes, algae, invertebrates and fish.
- Management of environmental flows in the context of competing demands for water.
- Development and implementation of monitoring programs to assess the ecological condition of aquatic ecosystems.
- Design and ecological assessment of waterway restoration projects.
